摘　　要：民用飞机在巡航和机动飞行过程中经常会不可避免地受到阵风或大气紊流的影响,而产生气动力和力矩,带给飞机的是不希望的附加过载,致使飞机在飞行中产生振动、颠簸等现象。针对这一问题,采用一种新的L_1自适应控制方法来设计阵风减缓控制系统。文章首先概述了L_1自适应控制方法的基本结构;然后构建存在大气紊流影响时的飞机模型,并具体结合L_1自适应控制方法,设计民机阵风减缓控制律;最后对所设计的控制系统进行了仿真验证,结果表明:所设计的L_1自适应控制器能够起到良好的阵风减缓作用。Civilian aircrafts often are inevitably influenced by gusts or atmospheric turbulence in the cruise and maneuver flight process, then generate aerodynamic forces and moments, bring undesirable additional overloads, lead to the phenomenon of oscillation and bumps. To solve this problem, adopt a new adaptive control to design gust load alleviation control system. Firstly, giving overview of the basic structure of L1 adaptive control; then build the model of civil aircrafts when atmospheric turbulence influence, and combine with L1 daptive control to design gust load alleviation control law; finally, carry on simulation verification to the control system, the simulation results show that, the L1 adaptive controller can play a good role on gust load alleviation.
